Lets's calculate LCM of 80,12,21,432

2 80, 12, 21, 432
2 40, 6, 21, 216
2 20, 3, 21, 108
2 10, 3, 21, 54
3 5, 3, 21, 27
5, 1, 7, 9

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 5 x 1 x 7 x 9 = 15120

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/15120

Therefore, the GCF of Fractions 83/80,86/12,35/21,82/432 is 1/15120

Least Common Multiple of 80,12,21,432 with GCF Formula

Least Common Multiple of 80,12,21,432 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 80,12,21,432 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,12,21,432) = 1

common factors(in case of two or more numbers have common factors) = 576

GCF(80,12,21,432) x common factors =1 x 576 = 576

LCM(80,12,21,432) = ( 80 × 12 × 21 × 432 ) / 576

LCM(80,12,21,432) = 8709120 / 576

LCM(80,12,21,432) = 15120
